drap660 Posted July 7, 2010 Report Share Posted July 7, 2010 I have a set of 39mm pwk Im running on a 10mm cub. The needles that came with the carbs say H9C. I have heard that different needles make a difference. Which needles should I be running? Quote Link to comment Share on other sites More sharing options...
STINKYDELUXE Posted July 7, 2010 Report Share Posted July 7, 2010 I ran a CCK or CEK (I can't remember which but they are only 1 off) on my 10 mil super and later switched to a 10 mil cheetah and it was still good, that is running 110 Octane.

badassbanshee479 Posted July 12, 2010 Report Share Posted July 12, 2010 are these gravity fed or pumper carbs? sounds like you have pumper carb needles in them... are you running gas or alky? Quote Link to comment Share on other sites More sharing options...
drap660 Posted July 12, 2010 Author Report Share Posted July 12, 2010 running gas. Gravity fed, no pumps. Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted July 12, 2010 Report Share Posted July 12, 2010 CEL Needles worked the best for me on gas..... and EGN needles seem to work the best on alky... for me anyway. Quote Link to comment Share on other sites More sharing options...
